Anechoic Chamber for Testing Quietness of New Energy Vehicle Air Conditioning Components
Technical Challenges
Acoustic performance testing and fault diagnosis for components such as air conditioning compressors and blowers must be conducted in low background noise environments.
Solutions
Design and build a dedicated test anechoic chamber equipped with a constant temperature and humidity control system and interfaces for precision acoustic measurement equipment.
Implementation Results
Background noise reduced to 30dB(A), test data accuracy improved by 35%, and product development cycle shortened by 20%.
Project Background
This automotive parts supplier specializes in the R&D and manufacturing of air conditioning systems for new energy vehicles. Noise performance of components such as compressors, blowers, and door actuators directly impacts the vehicle's overall NVH. Therefore, acoustic testing and quality inspection must be conducted under strictly controlled environmental conditions.
